| Abstract: | An experimental investigation was carried out in the BUAA D 1 low speed wind tunnel to determine the vane thrust vectoring jet effects on aerodynamic characteristics of the modern fighter model.Based on the advanced fighter configuration with double delta wing and elliptic body,the three vane thrust vectoring system is installed in it.The effects of longitudinal and lateral vectoring jet on the flow patterns around the fighter model and its aerodynamic behavior are studied in detail.The vectoring jet interactive effects from parameters including vectoring jet pressure ratio p0j /p∞, longitudinal and lateral deflection angles of vanes Dp and Dy, the width Wp of longitudinal vane are also studied. |
